It was a vision of one of my gods which cemented for me which religion I was going to join. In addition, I once had a god do a very concrete favor for me which enabled me to protect and help my mother, and once I had a personal interaction with a god which shook me to my core. By and large we go our separate ways, though. I rarely have things which require their attention, and they've not yet called in on our ties.

I drowned.
Thats an experiance that changes your life.
I remember a weird sensation like I was departing my body, wasnt scary at all.
Then I was revived on the beach.
So I had a near death experiance
Makes me appreciate every moment

I was meditating in my room with my favorite incense burning. I was transported to an imaginary realm I had yet to encounter. To me, that is the greatest gift my beliefs could bestow upon me. Great imaginary worlds, and new views which help me to further appreciate the beauty of nature. I don't know if you would count that as a spiritual experience, but it felt out of body to me...
